To (L7/Z when?, it may concern:

Be it known that I, HAROLD OoLBY, a citizen of the United States,residing at Spokane, in the county of Spokane, State of 1Washington,have invented certain new and useful improvements in Mop-lVringers; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to the art of scrubbing, and consists moreespecially in an improved wringer for mops or clothes whose details ofconstruction are set forth below, and which is illustrated in theaccompanying drawings, wherein- Figure 1 is a perspective view of thisentire machine, ready for use as a mop wringer. Fig. 2 is a centralvertical section showing the device in use and illustrating how a tubmay rest upon the base. The second view illustrates how a spring orsprings could be coiled on the rod which supports the bail, while thefirst view illustrates contractile springs as connecting the lower endsof the main levers.

Referring to the drawings, the numeral 1 designates a base, here shownas fiat so that a tub may rest thereon as seen in Fig. 2; and from thesides of this base rise two uprights 2, while to the rear extend twoside supports 3 which are connected at their outer extremities by atransverse rod 4. Pivoted in the upper ends of the uprights are twopairs of main levers 5, each preferably bent at an obtuse angle near itsupper end as at 6, and each preferably pivoted to the upright at a point7 within this bend. The two levers of each pair occupy reversepositionsso that their short u per arms lie close together and nearlyparallel when the long arms are forced apart as shown in Fig. 2.

Power is applied through a foot-lever 10 which preferably comprises thetransverse member of a U-shaped bail 11 whose side arms extend from thefoot-lever backward in parallelism over the base and are sufficientlyspaced from each other to span a tub of ordinary size. At their rearends they are pivoted as at 12 upon the rod 4, and if desired a s ringor springs 3() (see Fig. 2) may be coi ed on this rod and exert atendency to normally raise the foot-lever.

13 designate two toggles one at each side of the machine, whose outerends 14 are ,at their ends.

pivoted to the lower ends of the main levers 5, and whose inner ends arepivoted to each other and to the side arms of the bail as at 15. In Fig.1 I have shown two contractile springs 31 connecting the points 14 andstanding outside the mainlevers 5 and within the uprights. These springsmay be used in stead of the single spring 30, and if they are employedtheir tendencyv is to draw the lower ends of the main levers togetherand raise the foot-lever as explained below.

20 designate two rollers which may be of rubber, wood, or other suitablematerial, and these are fast upon spindles 21 which are journaled in theupper ends of the main levers. The said rolls 2() are cylindrical rollswhose outer surfaces are concaved to the extent of one-sixteenth part ofan inch,

thus making the diameter of said rolls in the center or at a pointequi-distant from the ends one-eighth part of an inch less than Saidconcave surface makes an arc or chord of a circle extending from theends of said rolls inward, and concaving toward the center of the rollsand thence out to the said ends. One of the spindles may be continuedinto a crank handle 22 if desired. 23 are gears which may also bemounted on these spindles if desired, and they are of such size andshape that they will intermesh When the faces of the rollers all buttouch each other. The parts are of desired proportions and materials,and if pre'- ferred the springs may be entirely omitted.

When this device is in use as a mop wringer, the tub usually sits uponthe base within the bail. As the operator lifts the mop-head out of thetub he raises it (still dripping) and lets it down between the rollers,and then by applying pressure to the footlever the toggles cause themain levers to swing and the rollers to be approximated so as to squeezethe mophead between them. If suflicient wringing is not accomplished byforcibly withdrawing the mop-head, the crank-handle may be used tosupplement this operation. When this device is used as a wringer forclothes, the bale is depressed further than when used as a mop wringer,so that its foot-lever rests upon the floor or the base as seen in Fig.2, and willretain this position where it will not interfere with theinsertion or removal of the tub, above which latter the rollers standand are operated in the usual way. If the spring 30 is employed, theremoval of the foot allows the bail to rise TOO and the rollers to openat any time; if the springs 3l are employed, itis possible to depressthe foot-lever until the toggles are straight or their central pivotshave passed a straight line between their end pivots, when the springs3l will hold the foot-lever depressed; and if no springs are employed,it will be necessary to lift the foot-lever before inserting the articleto be wrung out.

Itis possible to use this device in the ordidary operation of washingclothes and the like. When so employed, the tub containing the wetpieces of wash is placed on the base, and said pieces are successivelyraised by hand or with the laundry stick and inserted between therollers, the pressureis then applied by the foot-lever, and by turningthe crank the clothes are wrung out and forced up where they can bepassed on to the next operation-the water wrung out meanwhile runningback into the tub.

What is claimed as new is:

The herein described wringer, the same comprising a base having spaceduprights, duplicate pairs of main levers of which each lever is bent atan obtuse angle and pivoted at its bend to one of said uprights, tworollers connecting the up er ends of the levers, gears on the ends osaid rollers a crank handle on the shaft of one roller, toggle leversconnecting the lower ends of the levers of each pair, contractilesprings drawing said lower ends normally toward each other rigidsupports projecting to the rear from sai uprights, a transverserodconnecting the outer ends of said supports, and a U- shaped bail whoseends are pivoted on said rod, whose sides are pivoted to the centralpivots of said toggles and whose transverse central piece forms afoot-lever, the position of said rod being such that when. saidfootlever is completely depressed the central pivots of the toggles arebelow a line through their end pivots, for the purpose set forth.

YIn testimony whereof I hereby affix my l signature in presence of twowitn esses.
